Help guys !

Sky box has now been scramblef for a week . Talk Talk confirm network 100 % ok . Tried 3 different lan cables all work on other things . Skybox light up at the back . Channel list updated 3 times now . Rebooted and re set router 5 times . Skybox disconnected from power 5 times also . Tried 5 different codes from seller all still scrambled . Free channels work ok .. Tried a free line and managed to get sky sports 1 on for 10 mins then went to scrambled again . Cline says online .. Any help would be good . Was working fine till week ago

Seller not from eBay by any chance, get a test line from someone on here if it works the guy you bought it from is spinning you a line

Been with the same seller for 3 years now . No problems at all till now . Had 3 seperate yearlines off him with no pr2 and to be fair he gets back to me within the hour . Also had about email between us . The seller is sound . As i said in my post had a few test lines .. All but one didnt work . The one that did work only unscrambled sky sports 1 ... . Ideas ??
